RIDGE-SADDLE.

Specification of Letters Patent. 1 Patented Aug. 9, 1921.

Application filed. April 21, 1919. Serial No. 291,747.

cation, reference being had to the accompanying drawings forming a part thereof.

My invention relates primarily to asbestos cement shingles, particularly such angular shingles as are used for ridge saddles or cresting, corresponding to what are known as ridge rolls, when made in curved or semi-cylindrical form.

One object of my invention is to produce an asbestos or composition shingle, having a uniform thickness throughout the main portions thereof, but provided with downwardly extending flanges along the sides, and a thicker flange at one end thereof, which stiffen and strengthen the shingle in the form of a ridge saddle without materially increasing its weight.

Other objects of my invention will be apparent as the description proceeds.

In order that my invention may be fully understood, I shall now describe the same in connection with the accompanying drawing forming a part of this specification, and shall then point out the novel features thereof in the appended claims.

Referring to the drawing, Figure 1 1s a perspective view of a pair of overlapping angular ridge saddles which is made according to and embodies this invention.

Fig. 2 is a side elevation of one of these saddles.

Fig. 3 is an end elevation of thesame looking at the flanged end of the saddle.

Fig. 4 is an end elevation of the same looking at the unflanged end of the saddle.

Like characters of reference designate corresponding parts in all the figures of the drawing. I

This ridge saddle is molded of an asbestos and cement mixture and comprises two flat sides 10 and 11 of uniform thickness joined together at a desired angle. These sides are wider at one end than at the other. At the wider end are inwardly projecting flanges of suitable width which are substantially square in cross section, the inner edges 12 of which are but slightly greater in lengththan the width of the shorter end of the sides 10 and 11. The lower ends of these end flanges lie in a line parallel with an imaginary line which would form the base with the saddle sides 10 and 11 as the sides thereof.

There is no flange at the other end of the saddle, but longitudinal flanges depend ver-v tically from the lower edges of the sides, which flanges flare from no depth at the narrow end of the saddleto the depth of the end flanges at the other end which they join and are continuous therewith. The lower edges of the sides and outside of the longitudinal flanges lie in vertical planes.

This construction provides a light ridge saddle which is inexpensive to manufacture,

is fire proof, and has a highroof insulating value. Its parts are so proportioned that when overlapped as shown in ,Fig. 1, they fit togetherto form a weathertight capping for a roof ridge. The unflanged ends of the sides of these saddles lie against the roof surface onopposite sides of the ridge of the roof. The inner edges 12 of the end flanges fit tightly against the outer surface of the sides 10 and 11 and are of a length coincident with the width of the sides at the lines of contact. These end flanges have considerable width so as to make this joint strong and weather tight and to give the finished structure a more massive appearance. covered with these saddles is also and attractive appearance.

Having thus described this form of my invention, I do not wish to be understood as being limited to the exact details of form and arrangement of but what I claim and desire to protect by Letters Patent is:

1. A ridge saddle of an asbestos and ceof neat .ment mixture comprising angularly dis-' posed flat sides of substantially uniform thickness but tapering in width, inwardly extending flanges at the wider end thereof and longitudinal flanges connecting at one end thereof with said end flanges and being tapered toward the other end thereof. j

2. A ridge saddle of an asbestos and ce" ment mixture comprising angularly disposed flat sides of substantially uniform thickness but tapering in width, inwardly extending flanges having a substantial width at the wider end thereof and longitudinal flanges of narrower width connecting at one end thereof with saidend flanges and being tapered toward the other end thereof.- I 3. .A. ridge saddle of an asbestos and ceof a triangle.

The ridge parts herein set forth,

ment mixture comprising angularly disposed flat sides of substantially uniform thickness but tapering in Width, inwardly extending; flanges having a substantial Width at the Wider end thereof and longitudinal flanges of narrower Width connecting at one end thereof with said end flanges and being tapered toward the other end thereof, the length of said end flanges being substantially the same as the Width of the narrower 10 part of said sides.

Signed this 11 day of April, 1919.
